About this tool
Generate and inspect HTTP headers online to debug API clients, bots, and browser-like requests in seconds. This free HTTP headers tool is useful when you need clean request templates for `curl`, Postman, or backend test scripts.
You can quickly compare user-agent presets and verify standard fields before shipping integrations. Teams often use this utility to reduce avoidable 4xx errors caused by malformed or missing headers.
